It is the first time that event organisers Treble Ace Events have brought the show to Peterborough, giving fans the chance to snap up memorabilia from their favourite sci-fi and cult film and TV shows and meet the stars.

The line-up of celebrity sci-fi and cult TV and film stars also includes:

• Colin Baker, the sixth Doctor in Dr Who,

• Sylvester McCoy, the seventh Doctor,

• Paul McGann, the eighth Doctor,

• Honor Blackman, The Avengers star and Pussy Galore actress, and

• Stephanie Beacham, who played Countess Bartholome in Star Trek

Ticket prices vary according to admission time and whether there is a preference to have an autograph or photograph with a celebrity.
